Copy code

fun <T> UserApi.map(mappingF: (UserApi) -> T) : T  = mappingF(this)

then

Copy code

UserApi("a", 1, "b").map { User(it.name, it.age) }

you are just redefining

let

map

makes no sense here because

UserApi

is not a functor

True ... I forgot about

let

🙂 and I tried to not mention Functor as I had no intention to explain it
